No you would not need the diff drop. Actually there are quiet a few threads on here that recommend NOT using the diff drop even if you are lifted 3" due to bad design or bad characteristics with our trucks.

Those springs are a little more stiff and will give you about 1.6 inches lift on the 0 setting and about 2.5 inches at the .85 setting. The advantage being that you don't have to preload the springs as much. Both good options, but the eibach springs that you linked are just more money to spend and you will go under or over your desired 2".

But they ride sooo nice!! The Bilstein 5100's at 0 with the Eibach coils pushes the 2" mark (just under) and when coupled with a 1.5" AAL in the rear, rides very nice!
